Yeah. It seems like kids end up with the library DVDs a lot and they end up scratched up way before their time. My DVD library doesn't seem to have a longevity problem.
I am not sure I can tell a difference between 4k and 1080p at the distance I usually sit from the TV. I guess I'd have to see it in person. The thing is I just got around to finally getting a decent HD screen last year so I don't plan on reinvesting for a while. I guess by then 4k will be cheap and standard and I won't care.
